You forget how comfortable you get with some things. My tooth-brush, for example. It is right next to my sink that I can’t get to at the moment. It isn’t a big deal but I bought a temporary one while we are evacuated and it isn’t right! the bristles are not the same and it isn’t electric. I didn’t realize how attached I was to it until this morning when I was brushing my teeth and I thought, I really want to get back to using my tooth-brush. Maybe it is some metaphor for wanting to return home or maybe it isn’t that deep. I could just be I like my tooth-brush.
